Shortening shock length

[Sarcvicious]

To my understanding, stock shocks on the 82 Gs650 is 13. Would it be possible to fit 12 inch shocks? Im not asking for a lesson in geometry and trail. I realize shorter shocks would be increasing my trail.

Basically, I have 12 inch ohlins that I just installed on my sporty, but they’re not the ones I want. I’m wondering if I could use these shocks on the shafty (I’m trying to turn this into a cafe racer). I know nothing about shaft drive and I’m not sure if there’s something I should be considering before changing the stock shock length.

And yeah Ohlins might be overkill but if I can’t justify reusing these shocks then I can justify getting the shocks I want for my sporty.

thoughts? Opinions?

12 inchers will work, but be aware of the stress on the front propshaft UJ. Ideally, it should run straight for as much of the time as possible. A 1" drop at the shocks might not be enough to bother it overmuch.
Certainly, I'd not fit anything shorter than 12".

My opinion, for what that's worth, You'll never know the difference except possibly in seat height. Heck wouldn't stock 13" shock with spring set at lowest pos. be about the same as a 12" shock with the spring set to the highest pos.

Slower steering, a tendency to push the front end when cornering hard, and less ground clearance will be the main side effects.
If this is a cafe racer conversion mainly focused on looks then the tradeoffs may be ok for you. If you looking at actually riding it halfway hard, then it's a bad idea.
Either way, the Ohlins seem a bit of a waste. Why not just sell them?
